Rev 1:8-18
(8) I am Alpha and Omega, the beginning and the ending, saith the Lord, which is, and which was, and which is to come, the Almighty.
(9) I John, who also am your brother, and companion in tribulation, and in the kingdom and patience of Jesus Christ, was in the isle that is called Patmos, for the word of God, and for the testimony of Jesus Christ.
(10) I was in the Spirit on the Lord's day, and heard behind me a great voice, as of a trumpet,
(11) Saying, I am Alpha and Omega, the first and the last: and, What thou seest, write in a book, and send it unto the seven churches which are in Asia; unto Ephesus, and unto Smyrna, and unto Pergamos, and unto Thyatira, and unto Sardis, and unto Philadelphia, and unto Laodicea.
(12) And I turned to see the voice that spake with me. And being turned, I saw seven golden candlesticks;
(13) And in the midst of the seven candlesticks one like unto the Son of man, clothed with a garment down to the foot, and girt about the paps with a golden girdle.
(14) His head and his hairs were white like wool, as white as snow; and his eyes were as a flame of fire;
(15) And his feet like unto fine brass, as if they burned in a furnace; and his voice as the sound of many waters.
(16) And he had in his right hand seven stars: and out of his mouth went a sharp twoedged sword: and his countenance was as the sun shineth in his strength.
(17) And when I saw him, I fell at his feet as dead. And he laid his right hand upon me, saying unto me, Fear not; I am the first and the last:
(18) I am he that liveth, and was dead; and, behold, I am alive for evermore, Amen; and have the keys of hell and of death.
Christopher: When you read 8-18, you put the entirety of the message and the identity of the speaker in context. I cannot see that it could be anyone else but Christ. He was alive, died for our sins, and rose again. In chapter 22, we see this statement of alpha and omega and Jesus specifically says that this is Him.
Rev 22:13-16
(13) I am Alpha and Omega, the beginning and the end, the first and the last.
(14) Blessed are they that do his commandments, that they may have right to the tree of life, and may enter in through the gates into the city.
(15) For without are dogs, and sorcerers, and whoremongers, and murderers, and idolaters, and whosoever loveth and maketh a lie.
(16) I Jesus have sent mine angel to testify unto you these things in the churches. I am the root and the offspring of David, and the bright and morning star.
Hope that helps.
